sorry, won't be of any help, but would like to contribute vote for extending support over wider range of mobile smartphones. I'm also after QTEK S100, but I'm not sure if this is supported or not. There are bundles with this phone that act also as Navigation systems
and those kits are incredibly useful - and it would be really nice to support them under Pluto. I know it's a tight scehdule till stable release, but IMHO if features will be limited to only few devices then it won't sell good enough...
